One of my minor goals for 2020 is to switch all the gear I carry around to being USB-C PD. I've been doing some research on the subject, so just thought I'd throw my 2 cents in (some of this stuff mentioned in other comments). There's a pretty good site, https://www.chargerlab.com/ (see also: https://twitter.com/chargerlab ) that's dedicated to reviewing charging peripherals. I started off the year with an Innergie 60C, which has worked great for everything I've thrown at it and is tiny (55mL volume, 88g, 60W USB-C PD). It was on-sale recently, but even at full price has been worth it for me. (Although the newer RavPower PD Pioneer 61W is a good alternative that's almost as small and 1/3 the price.) I'm looking forward to adding the upcoming Sanho HyperJuice 100W charger (about twice the size, but a bunch more ports) https://www.kickstarter.com/projects/hypershop/hyperjuice-worlds-first… Instead of the Anker PD1 18W, for a small charger, I use the Anker PIQ 30W - it's very slim, which actually makes it much easier to carry around. Also, the IMO folding plugs (and extra juice) are definitely worth the extra volume. Recently, for my Mavic Pro 2, I just got a cheap Cablcc USB-C to Plug Receptacle Charger cable and a RCGEEK car charger that seems to work well as a nice 2-in-1 (it only saves a tiny bit of volume and weight over the wall charging but it also provides car charging). Also, although I'm unsure of how often I'll need it, I got a…

Other USB Charger review repositories: https://lygte-info.dk/info/ChargerIndex%20UK.html https://www.chargerlab.com/category/reviews/reviews-chargers/ Both are great. I especially love the Oscilloscope analysis of the noise characteristics and safety review on lygte-info.dk

There is a detailed teardown here: https://www.chargerlab.com/teardown-of-apple-140w-usb-c-power-adapter-… And a discussion here: https://discussions.apple.com/thread/256262949?sortBy=rank And you will notice that the regular power adapter cable is not compatible with the new 140W charger: https://www.apple.com/au/shop/product/mw2n3x/a/power-adapter-extension…

I don't know if this link will work - https://www.chargerlab.com/wp-content/uploads/2022/06/2022061718103949… but that metal round pin thing is a ground; and the three-prong cable connects to it.

Or their chargers! https://www.chargerlab.com/apple-18w-usb-c-power-adapter-a1695-teardow…

What's interesting about it is that it supports SPR AVS, which is a new USB power delivery spec. I'm not aware of any other chargers that support this. https://www.chargerlab.com/complete-pd-3-2-spr-avs-specification-inclu…

I think "active" HDMI is similar to the expensive USB3 cables, which are basically fibre optic cables in disguise https://www.chargerlab.com/the-way-to-metaverse%EF%BC%9Fteardown-of-me…

ChargerLab does a lot of charger teardowns. Not sure which 30W Anker you were referring to, but here is one: https://www.chargerlab.com/teardown-of-anker-30w-usb-c-gan-511-charger…

If you want something in lab quality, the Power-Z KM003C [1] is a decent model. I use mine to troubleshoot USB-C PD docks. You can, however, blow up stuff with the Power-Z, too. [1]: https://www.chargerlab.com/introducing-the-brand-new-power-z-km003c/

Some cables have a computer in them [1] [2] [1] https://www.theregister.com/2013/03/04/cpu_inside_apple_video_adapter/ [2] https://www.chargerlab.com/two-arm-cpus-are-inside-teardown-of-apple-t…

I don't have one myself yet, but the Power-Z KM002C [1] looks like it can do most/all of that. There's an example on their unboxing video [2]. [1]: https://www.chargerlab.com/power-z-km002c-is-now-available-on-amazon/ [2]: https://youtu.be/RVMxe_NIDJI?t=2m20s

https://www.chargerlab.com/category/power-z/ These read out the e-marker and tell you the supported power delivery and USB data speeds. The irony that their product comparison table has 30+ rows should not be missed!

Hi, this is Ben from ChargerLAB. I am the author of this terrible article. I promise I will do better next time. Yes. This is Chinese version. It's "Triple C" certified instead of UL certified. The components might be different across different versions but we are not certain. The next time we will try to have a comparison between the same products aimed for differnet regions. You can checkout the teardown of an US version 60W Anker USB-C charger from this link. http://www.chargerlab.com/archives/539.html

http://www.chargerlab.com/archives/539.html This one is for laptops. Very compact and provides 60W. I use it with Lenovo X1 Carbon.

AMD CPUs typically have a very accurate SoC power measurements that's within 95% of reality. Obviously that is not the case for the M1 Max, which is not abnormal. This is probably because of the offsetting Apple does to avoid counting RAM power consumption, storage power consumption, etc..., that on the M1 Mac Mini amounts to something like 5W. Yes, using wall power masks the efficiency of the charger. That said, the charger is >94% efficient : https://www.chargerlab.com/apple-87w-usb-c-power-adapter-a1719-teardow… VRM efficiency at the middle-power range is generally >95%. On the other hand, using wall minus idle also has some advantages - you don't take into account the baseline power consumption of the memory controller, the baseline power consumption of the GPU, or the PCI/storage controllers, or the baseline power consumption of the USB controllers, and so on and so forth - that's easily 2-4W even on an M1, on a Ryzen chip this is included in package power, whereas it's not for the M1 Max. Because of that I judged the two numbers to be the closest to each other, and the minimal power consumption losses are more than offset by excluding a fair amount of power consumption that is reflected in the package for an AMD chip (and indeed any chip). I didn't explain and justify all of this because I didn't have the time to do so and I don't think it was necessary to clutter up the text this much. I'm not cherry-picking either. There is a…
